Product Description

This is an ENGINE TOP END REBUILD KIT and MACHINING SERVICE for the Honda TRX 125 Fourtrax fourwheelers.

PLEASE NOTE:This is a remanufacturing service of the cylinder that you're mailing in for us to machine. Your cylinder must be a good cylinder with enough room in the sleeve to machine to the next oversize. If the sleeve in your cylinder is already bored to the max size or is damaged, cracked, etc, we offer a re-sleeving service for an additional fee. Please contact us to discuss details. You will be required to remove the gasket material from the bottom of the cylinder prior to mailing it in. If you want us to remove your gasket from the cylinder, you will need to pay an additional $15.00 gasket removal fee. We also offer a bead blasting service of your cylinder for an additional $20.00 fee, if interested.

Here's what's included with this kit and machining service:

You mail in your cylinder to us, and we'll machine it and send it back to you in the kit.

We'll bore and hone your cylinder to the next oversize.

We'll include a matched oversized piston and ring kit which includes piston pin and circlips.

We'll include a top end gasket kit.

We'll include instructions for proper break-in procedures for your new top end rebuild.

This kit will come ready to bolt on for a quick and easy top end rebuild.

***WE ALSO OFFER A CLEANING AND BEAD BLASTING SERVICE FOR YOUR CYLINDER FOR AN ADDITIONAL $20.00 FEE. PLEASE CONTACT US IF YOU'D LIKE TO ADD THIS ADDITIONAL SERVICE TO YOUR ORDER.***
